Typical products include various photographic films, photographic papers, magnetic tapes, and the like.
以下、本発明の実施態様を添付図面に基づき詳細に説明
する。Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
第１図は本発明の一実施態様を示す概略断面図である。FIG. 1 is a schematic sectional view showing an embodiment of the present invention.
ウエブ２は、複数本のガイドローラ４間に装架されて所
定の方向（矢印Ａ）に一定の速度をもって搬送される。The web 2 is mounted between a plurality of guide rollers 4 and conveyed in a predetermined direction (arrow A) at a constant speed.

先端にはエッジ６が形成されている。A blowing nozzle 1 is arranged between the guide rollers 4 so as to face the surface of the web 2 on which dust should be removed. The blowing nozzle 1 has a slit 3 extending in the traveling width direction of the web 2, and an edge 6 is formed at the tip of the slit 3.
そして、前記スリット３の底部に設けられたチャンバー

れる。Therefore, a thin film layer of air formed by the pressurized air is formed between the web 2 traveling in the direction of arrow A and the edge 6, and the web 2 has a thickness of about several μm by appropriately setting the pressing force. It is transported while floating at a constant interval.

また、前記ウエブ表面に付着した小さい付着物は、前記
加圧空気によって吹き飛ばされ除去される。Here, since the surface adhered matter 10 adhered to the surface of the web 2 to be dust-removed is directly trapped by the edge 6 provided at the tip of the blowing nozzle 1, even foreign matter firmly adhered to the surface of the web is removed. You can do it.
Further, the small adhered matter adhered to the surface of the web is blown away and removed by the pressurized air.
更に、前記エッジ６を超硬合金やセラミック等の硬い材

をより効果的に削り落とすことが出来る。Furthermore, if the edge 6 is made of a hard material such as cemented carbide or ceramic, it is possible to more effectively scrape off foreign matter that is firmly fixed to the surface of the web.
したがって、前記ウエブ２の表面付着物除去に際して
は、該ウエブ２の表面と前記エッジ６とが当接しないの
で、前記ウエブ２の表面にスリ傷及び静電気等が発生し
にくい。Therefore, when removing the deposits on the surface of the web 2, the surface of the web 2 and the edge 6 do not come into contact with each other, so that scratches, static electricity, and the like are less likely to occur on the surface of the web 2.

は言うまでもない。The blow-out nozzle 1 may be covered with a case for preventing scattering to prevent the once removed adhered matter from adhering again to the surface of the web after the adhered matter is removed. Needless to say, the shape of the blowing nozzle 1 is not limited to the shape of the above-described embodiment, and various shapes may be adopted as long as the adhering material can be scraped off while the web 2 is floating.

も取り去ることが出来る。(Effect of the invention) As described above, according to the present invention, one side of a running long web is brought close to a blowing nozzle that extends in the web width direction and has an edge portion at the tip, and while the web is levitating, By the method of removing dust of the web, which is characterized by peeling off the deposits on one side of the web by the edge, small deposits attached to the web surface without physical contact with the web surface, or even strong deposits Can be removed.
したがって、前記ウエブ表面にスリ傷を発生させること
無く、安価で効率の良いウエブの除塵方法を提供するこ
とができた。Therefore, it is possible to provide an inexpensive and efficient method for removing dust from a web without causing scratches on the surface of the web.
次に、実施例および比較例により本発明方法の効果を一

Then, 30 parts by weight of an epoxy resin (epoxy equivalent of 500) was added and uniformly mixed and dispersed to prepare a magnetic coating solution. did.
その結果は第３表の通りであった。 The results are shown in Table 3.

果は第３表の通りであった。(Comparative Example) A magnetic coating solution was applied to a web (Sample Nos. 15 and 16) that was not subjected to dust removal treatment under the same application conditions as in Example 2, and the number of foreign matter trapped at the edge of the coating device 7 and the foreign matter were measured. The number of coating stripes according to was visually observed. The results are shown in Table 3.
